' IMPROVEMENT INRECIPROCATING CHURN-DASHERS.

Specification forming part of Letters Patent No. 142,007, dated August19, 1873; applicationfiled March 26, 1873..

To all whom it may concern:

Be it known that I, TIMOTHY EARLE, of Valley Falls, county ofProvidence, in the State of Rhode Island, have invented certain new anduseful Improvements in Churns, of

- which the following is a Specification:

The nature of my invention consists in combining with the air-pumpchamber of a churndasher a combined cap and valve, which can be easilyremoved when desirable. The object of this device is to furnisha churnwith a dasher which shall serve as an air-pumpin g dasher whilechurning, and yet admit of being used as anordinary dasher forbutter-working, by simply removing the capand valve.

The drawing represents my invention in vertical section.

Let E represent the barrel of the churn, which may be made of anysuitable size and style. A is a concaved. dasher, of whichG is a hollowhandle, at the upperend of which I place a screw-cap, G. Within this capI place the valve 1), which is held up by the spring a and stud b, sothat as the dasher goes down it closes and prevents the air fromescaping; but when the dasher is drawn up the air can rush in to fillthe space under the dasher. Thus the handle G of the dasher becomes anair-pump, and constantly throws air into the cream.

When buttrifaction takes place, the forcing in air is an injury, and toprevent it I remove the cap 0 and its valve. By this change the dasherbecomes suitable for working over the butter and freeing it from themilk. 7

I claim as my invention-- The combination with the hollow dasherhandleG, the cap and valve 0 and 1), ar-' ranged substantially as described,and for the purpose set forth.
